Grange, Ga, a corporation 1 of: Georgia I Anrl afion Nov m r 1. 1asa;. iai1 m mm 9 Glaims. (Cl. 19-439) I This invention relates to top clearers and is illustrated as embodied in along .dfaftspinning frame. U I

Although this inventi'ofl is adaptable to all existing drafting systems in" use, it is designed especially to. meetth'e} conditions that have been brought about as a" result of the introductionof long draft spinning system's; 7 h

This invention is also adapted for use in the long draft roving proces'sQWhich is similar to the system in use on the spinning frame;

An object of this invention is to aid in overcoming cleaning problemsthatlliavearisen as a result of various "synthetic materials being used for covering drafting rolls instead of the conventional calfskin and sheepskin'that are in common use at the present time; Another object'of this invention isto facilitate the removal of waste that collects between the top front roll, the clearer cloth, and the apron which is usually driven by the middle top roll.

Still another object of this'invention is to prevent the waste from being carried" forward with the'roving. This isespecially true in regard to thellongdraftspinning systems where the waste collects in the wedge-shaped space between the leather aprongj'clearer cloth, andtop front roll. A further object of the invention is'to reduce the breakage of ends between the deliverygrolls n t e t v 1-enW Qhlivi1 es tiduetq Was r a d m vem n iitl e'r vin es le the delivery rolls;- 'Thethorough cleaning given to thelong draft system by thisinventionwill decrease the amount of defectiveyarn caused by the "waste passing forward with tin'aflxdving to form 'sl'ubs, gouts, and -eyebrowson -the yarn as it is spun. f i

This invention requires less cleaningor picking than the ordinary olearers in use at the present time. The invention greatly reduces this operation. 7 The waste collects inv the space between the top front roll and the downwardly extending portion of the clearer cloth and is easily removed when it is necessary to clean the top clearer or pick it as this operation is called.

by spinning frame attendants today. The downwardly extending portion of the top clearer inthe wad of waste frequently falls out on the yarn that is bein'g spun and, in many cases, breaks down one or two ends'as it falls.

After the roving leaves the front rolls "H and I2, it is spun into yarn by a spindle and traveler in the usual mannerrnot show-n. 7

The illustrated clearer has a napped cloth l5 secured to it by means of the broad staples i5 and IT. This fabric is preferably constructed with a cotton warp and woolen filling. The downwardly extending portion l8 of the clearer cloth may, if desired, be made by forming a tuck in the cloth and sewing it together at the base. This tuck fits down in the space between the top front roll l2 and leather apron 8. The upper and lower portions of the clearer cloth I5 consists of one piece of fabric folded around the staples I6 and I1 and, if not constructed circular, is sewed or otherwise fastened together, which gives two layers with a small space between the W0. 3 I

The perspective view of the clearer shown in Fig. 2 illustrates how the stitch I9 is inserted in the fabric. The tuck I8 is made in the cloth l5 and the stitch is inserted in the base of the tuck and in the same plane as the lower portion of the cloth I5. Cutouts 20 in the clearer board I4 are the usual type designed to fit over the usual roll saddles in spinning frames. The cutouts 2I in the clearer board M are of the usual type designed to hold the clearer in position on the frame.

The enlarged plan view of a portion of the top clearer shown in Fig. 3 illustrates how the staples I6 and I! hold the clearer cloth I5 on the clearer board l4. The cloth I5 is folded'over and the ends, if the cloth is not wovencircular, may be sewn together. The tuck I8 is formed and the stitch I9 is inserted at the base and inthe same plane as the lower portion of the cloth I5. The staple I6 is placed in the end of the cloth next to the tuck and is driven into the board I4. The staple .I I, not shown, isinserted in the continuous strip of cloth and driven into the opposite side of the board I4.

As the leather aprons I and 8, shown in Fig. 1,' are driven by the rolls 5 and B and are in constant contact with the cotton, a considerable amount of waste is carried forward by them. The waste from the top leather apron 8 collects in the space between the clearer cloth I5,- top leather apron 8, and the top front roll I2. As the top front roll I2 revolves at a high rate of speed, it has a. tendency to carry this Waste around with it to be deposited on the roving that is being spun into, yarn at the delivery point. It will be noted that the tuck I8 in the clearer cloth I5 will prevent this waste from passing downward due to the movement of the top front roll I2 and also permit a good deal of waste to collect, before it becomes necessary to pick the clearer. The prevention of this waste from passing downward accomplishes the results that are claimed for the invention.

Although only one illustrative embodiment of the invention has been shown and described, it is not intended that the scope of the invention belimited thereby, nor otherwise than by the terms of the appended claims.

What. is .claimed is:

.1. In a textile machine having drawing rolls and aprons, a top clearer comprising a clearer board and a clearer cloth carried on the underneath side of said board and adapted to engage the upper rolls at the top thereof and a downwardly extending portion associated with said clearer cloth designed to fitbehind the front top roll and in front of a top apron of said machine.
